SIGNAL-LAMP SUPPORT.

Application filed September 8, 1921. Serial No. 499,320.

To all who-m it may Concern:

Be it known that I, GEORGE ELLIOT PERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Signal-Lamp Supports, of which the following is a specification.

This invention relates to signal lamp supports.

One of the objects of the invention is to provide an improved signal lampik support.

Another object is to provide an improved adjustable support for mounting a signal lamp on a post.

Another object is to provide a simple, reliable and inexpensive adjustable bracket for supporting a signal lamp.

Other objects and advantages will hereinafter appear.

An embodiment of the invention is illustrated in the accompanying drawing, where- 1n f Fig. 1 is an elevation of a post and lamp support, partly in section.

Fig. 2 is an enlarged partial section of the lamp and reflector support.

Fig. 3 is a section of the reflector bracket.

Fig. t is a front elevation of the reflector bracket, and

Fig. 5 is a perspective of the lamp socket and its position adjuster.

rIhe post comprises an elongated hollow casing 1, the lower end of which is adapted to be sunk into the ound or otherwise anchored in position. he upper end of the casing may be closed by a suitable cap 2 and the bottom may be closed by a suitable The casing may be of any desired length and cross section and may be formed from wood, pressed steel, cast iron, or other suitable material.

The inside wall of the casing is provided with a number of sets of inwardly projecting lugs or shoulders 4, 5 and 6. Lugs 4 and 5 support floor panels 7 and 8, respectively. These floor panels may be made of wood or other suitable material and serve to carry batteries 9 and act as partitions to divide the casing into separate compartments. 'Ihere may be as many floor panels as are required for the batteries necessitated by any particular installation.

The upper set of lugs 6 serve to support a asher or circuit interrupter V10. Any suitable flasher may be employed. One which has given excellent results is disclosed in c-opending application Serial No. 395,514; filed July 12, 1920.

The casing is provided with one or more openings in its side so that access may be had to the interior for the installation, inspection and removal of the batteries and flasher. In the embodiment illustrated one opening is employed and it is closed by a door 11. The door is secured to the casing by suitable means' such as hinges 12 and may be provided with latches 13 and a key actuated lock 14.

The upper end of casing 1 has a bracket 15 secured thereto. Bracket 15 is secured in place by suitable means such as screws 16, passing thru holes 17 in the bracket and threading into the post. A hole 18 passes through the cent-eroi the bracket. The wall of this hole is curved or -chamfered as shown.

Bracket y15 supports a reflector and lamp holder 20. The front of holder 20 is cupped to lit the rear of a substantially parabolic reflector 21 and the rear end thereof is somewhat spherical to fit against the beveled wall of hole 18. Reflector 21 is secured to holder 20 in any suitable manner The holder and reflector are adjustably held to bracket 20 by screw bolts 22. The heads of bolts 22 are set in recesses in holder 20, and the shanks thereof pass thru openings 23 in bracket 15 and aligned holes in casing 1. The nuts on the adjusting screw bolts are readily accessible through the door` in the casing.

The reflector holder, upon the loosening of bolts 22, may be moved in any direction j because of the universal joint provided by bracket 15. vlil/'hen the proper adjustment is secured the same may be maintained by tightening the nuts on bolts'22.

Within reflector 21, holder 20 supports a lamp socket 25 for a lamp 26. rlhe si tion of the lamp socket along the axis of the reflector is regulated by a screw 27. Holder 2O and the reflector have aligned holes 28 and 29 passing therethrough. Holes 28 and 29 merge into each other, the latter being somewhat larger than the former. Socket 25 slidably fits in hole 28 while a lug 30 of the socket slidably fits inhole 29. Lug 30 has a threaded hole therethrough for receiving screw 27. When v the socket is in position the head of screw 2'? abuts the rear of holder 20. Lug 30 prevents rotation of the lamp socket althou h the same is free to move longitudinal y along the axis of the reflector. The threading of screw'27 in 0and out of lug 30 varies the position of lamp 26. The conducting leads 31 may pass to the lamp vsocket through hole 29. l

Having described 'my invention what I i claim as new and desire to secure by Letters Patent, is

A signal lamp comprising a. flat face support; a lamp holder to support a lamp socket and having its rearsurface substantially spherical, a bracket having a dat 'ace and a hole therein to give access to the rear of a lamp socket and to provide a seat for the spherical end of the holder so that the holder may be pivotally moved in any direction relative to the bracket, and a bo'lt passing thru the support, bracket and holder or holding the device on the support and the bracket and holder together in any position.

\ In testimony whereof l hereunto subscribed my name GEORGE ELLIOT PERRY.
